Do CTRL+ALT+F1 and get to a terminal, login, and then run your upgrade
again (sudo aptitude dist-upgrade). I'm betting that it didn't
completely cleanly.
Also make sure that the ubuntu-desktop and ubuntu-standard packages are
installed, you might have done some uninstalls that pulled these
packages off which wouldn't have caused any problems until you upgraded
and they needed to pull in extra packages that would break you system.
